On the Classification of Schubert Varieties in Partial Flag Varieties
Abstract.
We generalize the classification of isomorphism classes of Schubert varieties in complete flag varieties G/B (E. Richmond and W. Slofstra, 2021) to a class of partial flag varieties G/P.
In particular, we classify all Schubert varieties in G/P where P is a minimal parabolic subgroup, and all Schubert surfaces which are two-dimensional Schubert varieties.
